DIES FOR TYING INTERSECTING WIRES.

SPECIFICATION forming part of Letters Patent N0. 755,185, dated March 22, 1904. Application filed February 26, 1903- Serial No. 145,120. (No model.)

1 the same, reference being had to the accompanying drawings, and to the figures of refer-- ence marked thereon, which form a part of this specification. V

This invention relates to dies for uniting or tying intersecting wires, being more expressly designed for tying the cross-wires in wire fencing and other fabric; and it consists in the peculiar association and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claim.

The object of the invention is to provide simple and efficient means for tying, by the use of a suitable knot, intersecting strands of wire to prevent lateral and longitudinal movement of said strands, the arrangement being such as to enable the forming of a secure knot which unites the crossed strands of wire without the expenditure of undue energy. The above-mentioned object is attained by means of the dies illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the inner faces of the dies, showing the concavities therein which direct the staple in forming the knot and the channels which receive the crossed wires between the meeting faces of the dies. Fig. 2 is a transverse section through the dies with the crossed wires and the tyingstaple between their opposed faces, showing the plunger which is employed in driving the staple into the dies in the operation of tying the knot. Fig. 3 is a transverse section through the dies, as on line 3 3 of Fig. 2. Fig. 4 is a perspective view of the knot embracing the crossed strands of wire. Fig. 5 is a perspective view of the crossed wires, showing the manner in which they are crimped at their point of crossing by the embracing-dies when saidv dies are brought together prior to the driving of the staple whichunites the wires.

Referring to the characters of reference, 1 designates the fixed die as adapted to be suitably mounted in a frame or support, so that the driving-plunger 2 may direct into the inclined way 3 in the end thereof, so as to drive the staple into the dies in the operation of tying the intersecting wires. Crossing the inner face of die 1 is a transverse channel 4, adapted to receive the vertical or stay wire 5 of the fence or fabric. Upon one side of the channel 4 in the face of said die are the two concavities, comprising the outer concavity 6 and the inner concavity 7 the curves of which are concentric and which are divided by the curved wall or partition 8 and are adapted to direct the ends of the tying-staple 9 so as to cause them to overlap or extend past each other in concentric curves-in the same plane, as clearly shown in Fig. 4. Also formed in the face of the die 1 is'a channel 10, which crosses channel 4 atright angles and also crosses the curved 'concavities 6 and 7, Said channel 10 at one end leading into the inclined way 3. The top of the partition 8 is sufficiently below the face of the die to escape the channel 10, as shown in Fig. 2.

In the inner face of the opposite die 11, which for convenience will be termed. the movable die, are the channels 12 and 13, which cross at right angles and coincide with the channels 4 and 10 when the dies are placed with their working faces together. Formed in the face of the die 11 is the recess or. depression 14, from the sides of which atone end lead the outwardly-curved or conoaved branches 15. The depth of the bottom of the branches 15 is below the plane of the transverse channel 12, so that the legs of the staple are directed over or across the wire'5, lying in said channel, and thence upwardly into the curved conoavities 6 and 7 in the face of the die 1, which direct the endsof the staple past each other in concentric curves and under the wire 20, as shown at 16 and 17 in Figs. 2 and 4. In the face of die 11 are mounted dowel-pins 18, which enter corresponding sockets 19 in the face of die 1, whereby a perfect registering of said dies is obtained when they are brought together in working relations. It is designed that die 11 shall be mounted upon some movable support and by any suitable means will be carried against die 1 to bring the faces of said dies properly together.

In the operation of these dies they are first brought together upon the crossed strands of wires 5 and 20, preferably, with the inclined way 3 extending horizontally. The staple 9 by any suitable means is then fed into said way, so as to straddle the horizontal wire 20 in the path of the plunger 2, which enters said way, forcing the staple in advance of it. As the ends of the staple encounter the beveled face 21 at the inner end of the way 3 they are deflected and caused to enter the concaved branches 15 of the depression 14 in the face of die 11, whereby they are directed over the wire 5 and into the curved depressions 6 and 7 in the die 1, which direct the ends of the staple under the wire 20 from opposite directions and in concentric curves, as clearly shown in Fig. 4, thereby effecting a secure knot which unites the intersecting strands and which requires but comparatively little power to force it into the tied position, owing to the fact that in forming the tie the staple is not caused to follow any abrupt ang es.

Having thus fully set forth myinvention, what I claim as new, and desire to secure by Letters Patent, is-

In a device for the purpose set forth, the combination of the opposed dies, one of said dies having inits face, channels adapted to receive the crossed wires and having curved concavities separated by a curved dividing wall and across which concavities one of said channels extends, the other of said dies having channels which register with the channels in the first-mentioned die and having a depression with laterally-extending concaved branches, which branches cross one of said channels and register with the opposite ends of the curved concavities of the die first mentioned.

In testimony whereof I sign this specification in the presence of two witnesses.
